Title: Plasma arc welding method for silicon steel plate
Inventor: TANAKA AKIRA
IPC: B23K9/00
Filed: 1985-08-05
Abstract: PURPOSE:To reduce a welding cost by irradiating diagonally a plasma arc in the weld line direction under a specified welding condition. CONSTITUTION:A torch 1 is provided diagonally against the direction of a weld line 3, and a plasma arc 4 is irradiated diagonally at an angle theta against a silicon steel plate base 6. In this case, attention is paid so that the arc 4 is not irradiated directly to an electric insulating film 7. Also, as a welding condition, a control is executed so that a welding speed is <=0.5-1.0m/min, an energy density is <=2.0X10<4>/cm<2>, and also a heat input quantity is <=150J/cm. An irradiation angle theta is set to about 5-10 deg.. The arc 4 is irradiated diagonally and also the welding condition is set appropriately, therefore, mixing of a slag to the insulating film 7 can be prevented. Also, a burn-through can be prevented, and a welding cost can be reduced by using the plasma arc.

Abstract: PURPOSE:To input and output information at a speed (n) times as high as the operation speed of a memory cell apparently, by inputting n-number of input signals to n-number of memory circuit blocks in time division and multiplexing and outputting output data. CONSTITUTION:In case of n=4, address signals A11-A14 are outputted to four output terminals O1-O4 of a demultiplexer DMX in time division and are latched in latch circuits during a one-cycle time tCYC to become latch address signals LA11-LA14, and latch output data DL11-DL14 are obtained. Since the hold time of latch address signals LA11-LA14 is longer than the time required for access, latch output data DL11-DL14 are obtained surely, and they are multiplexed in accordance with a clock signal phi, and output data DOUT of D1-D4 is obtained. Even if the holding time of address signals is shorter than the time required for access, every memory circuit block is accessed surely because address signals are latched during the one-cycle time, and input address signals are inputted to the memory circuit in a speed 4 times as high as the conventional speed, and output data is outputted in a speed 4 times as high as the conventional speed.

Filed: 1982-09-30
Abstract: PURPOSE:To prevent the unstability due to abrupt accelerator pedal operation from occurring by a method wherein an actual yaw acceleration obtained by a lateral acceleration sensor and a vehicular speed sensor is compared with the reference value and the movement of a steering mechanism is corrected based upon the result of said comparison. CONSTITUTION:A drag link 8 is connected to the output end of an actuator 9 actuated by a microcomputer 10.
